The first thing you should do is take the battery to a local shop or store and have it tested on their bench equipment. If your tractor sets for 10 days or longer it will begin to lose electrolyte and diminish charging capability. To remedy this, many of us get a float charger unit (not a trickle charger)and keep the battery constantly maintained so it is 100% ready when you need it. The DELTRAN BATTERY TENDER JR. is one of the better units. If battery tests bad -it won't sustain a full charge under load -then a new one is in order. While battery is out and disconnected, verify the wiring is all correct. Get a copy of the I&T FO-19 Manual. Trace wires with a VOM set to continuity, not a test light. Tractor sat for 2 years -no doubt it is dead unless maintained.
